Based on the diversity of today’s pup breeds, scientists think that the dog was produced by crossing several related species from the dog family. Among them, Charles Darwin [36] and the ethologist of Austria, Konrad Lorenz, had been the initiators of the idea of evolution, who figured the ancestors of the domestic doggy had been a wolf and a jackal. Today’s established opinion, supported by the outcomes of genetic analyzes, is definitely that the domestic pet developed from a small band of wolves, domesticated about 15,000 years ago.

It is not known just how the domesticated dog was held. It is possible that canines were the ones who made the first step. Namely, if crazy dogs began to be small enough to end up being unsafe, to visit human camps, discarded bones plus they could collect waste. Thus, people most likely tolerated them because they were washing their surroundings. It’s possible they have begun to fascinate, approach them, and domesticize them as guard dogs and companions then. It was only once agriculture has been progressing that the herds could be preserved. Or elsewhere: the canines adopted a smarter series in the wish of getting anything from prey.

The initial remains of a domestic canine were found out in Mesolithic sites in various places. It seems that the initial European breed was quite small and would generally be best in comparison to today’s small doggy.

Many breeds originate from a small number of animals, which leads to mating in kinship. The effect is different hereditary (genetic) illnesses common in some breeds, for instance hip dysplasia (specifically in German shepherds), epilepsy, ataxia, oculoskeletal dysplasia, and others
